Specification of Letters Patent.

15, 1915. Serial No. 50,836.

To all 'Lv/wm t may concern Be it known that I, RUDOLPH J. ALTGEL'I, acitizen of the United States, and a resident of South Bend, in thecounty of St. Joseph and State of Indiana, have invented certain new anduseful Improvements in Planters; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains tomake anduse the same.

This invention relates to improvements in planters,-the same being adivision of application for patent filed by me on the 26th day ofFebruary 1915, and designated by Serial N o. 10,788.

One object of my present invention is to provide disk furrow openers andseed covering means which shall be so mounted and relatively arrangedthat the dropping of the seed in front of the axes of the disks shall befcilitated, whereby the choking of the seed tubes with dirt shall beobviated, and the deposit of the seed in the furrow before loose earthhas had a chance to roll in between the disks, shall be insured.

A further object is to so mount double disk furrow openers that thedisks will be prevented from coming closer together than may be desired.

A further object is to-so mount double disks that the leading kedges ofthe disks will remain close to each other regardless of the extent towhich the bearings may become worn.

,A further object is to mount the double disks in such manner as toyallow the two disks to form a narrower wedge than is possible withother constructions of which am aware, and thus leave just sufficientspace to permit the seedto be dropped be.- tween them in front of theiraxles.

A further object is to provide improved means for mounting the coveringblades.

l/Vith these and other objects in view7 the invention consists incertainnovel features of construction and combinations of parts ashereinafter set forth and pointed fout in the claims.

In the accompanying drawings; Figure 1 is a side elevation illustratingmy improvements; Fig. 2 is a plan View; Fig. 3 is a sectional view on alarge scale; Fig. 4 is a detail View partly in section and partly beamis bifurcated and projects rearwardly so as to be disposed in a planeapproximately parallel with that of the main forward portion of thebeam. The beam may comprise two bars secured together and the rearbifurcated portion may be formed by spreading these bars apart.

Between the members of the bifurcated rear end of each beam 44k, theforward portion of a bracket 6 is rigidly secured, said bracketprojecting downwardly and rearwardly from its connection with the beamand is provided at its lower' end with an approximately horizontal,rearwardly projecting journal 7 for a purpose hereinafter explained.

The upper forward ends of the inclined arms 8 ofthe respective pairs arerigidly secured to the diagonal portion 5 of each beam 4 at respectivesides thereof. These arms may be made of resilient rods or bars and arenormally spread laterally from their connection with the beam. At theirlower ends, the arms 8 may be bowed laterally and then made to projectinwardly'to 'form approximately horizontal journals 9 for the hubs 10 offurrow opener disks 11, the journals 9 being so disposed relatively toeach other that the disks will be disposed at such angle to each otherto form a narrow wedge with the leading edges of the disks which formthe apex of the wedge in close proximity to each other.4 The hubs 10 areprovided with iianges 12' secured against the outer faces of the disks,and the inner ends of said hubs are made with rounded heads 13 whichproject through axial openings in the disks and bear againsty 'eachother, being lightly pressed toward each other by the resilient actionofthe arms 8. With such construction, the disks will remain together infront, during the operation of the planter, no matter how much thebearings may become worn. ln other words, the two disks will constantlypress against each other at their front or leading edges as long as theplanter is being moved forwardly, even though there may be considerableplay in the bearings.

By mounting the disks as above described, the pair of disks may be setto form a narrow wedge, it being only necessary to afford suliicientspace betwen them Vin advance of their axes to permit the dropping ofseed. rfhe seed spouts 1a are supported between the bifurcated rearportions of the beams i and are so disposed that they will dependbetween the disksof the respective pairs forwardly of their aXes andthus discharge the seed forwardly of the axes of the disks so that saidseed may be deposited into the narrow furrow before any loose earth hashad a chance to roll between the disks. A further advantage of locatingthe discharge ends of the spouts 14 forwardly of the axes of the disks,is that they cannot become clogged with dirt which might be thrownupwardly by the revolving disks.

Pairs of covering blades 15 are provided in rear of the pairs of furrowopening disks. Each pair of blades may be made from a single strip ofmetal, to the horizontal intermediate or connecting portion of which, acurved or segmental block 16 is secured. A sleeve 17 is mounted on thejournal 7 at the rear ends of the bracket 6, so as to have a limitedrockino` movement on said journal, and said sleeve is provided with Vanenlargement forming a curved seat 18 for the reception of the segmentalblock 16 and lto which said block is adjustably secured so that theactive portions of the covering blades may be adjusted vertically. Bymountingthe sleeves 17 so that they may have a limited rocking movement,the covering blades will be permitted to adapt lthemselves to theunevenness of the ground.

Having fully described my invention what l claim as new and desire tosecure by Letters-Patent, is z-f l 1. In a planter, the combination withVa frame and a beam attached thereto, of a pair of resilient armssecured to the beam and provided with inwardly projecting journals,furrow opener disks disposed between said arms and lhaving' centralopenings, hubs secured to the outside of said disks and mounted on saidjournals, said hubs ha-ving rounded heads projecting through the centralopenings of the disks and pressed against each other by said resilientarms.

popes of this patent may be obtained -vfor 2. ln a planter, thecombination with a frame, of a beam attached thereto, said beam having arear inclined-portion, inclined arms secured at their upper ends to saidinclined portion of the beam and provided at their free ends with inwardly projecting journals, furrow opener disks disposed between saidarms, and hubs secured to the outside of said disks and mounted on saidjournals.

8. ln a planter, the combination with a frame, and a beam attachedthereto, of -a pair of arms secured to said beam forwardly of its rearend and provided with journals, furrow opener disks mounted `on saidjournals, va bracket secured to the rear endof said beam, coveringblades, and an adjustable mounting for said blades on said bracket.

4. ln a planter, the combination with a frame and a beam attachedthereto, said beam having a bifurcated rear end, of arms secured to saidbeam and provided with journals, furrow opener disks disposed betweensaid arms and mounted on said journals, and a seed spout mounted in thebifurcated portion of the beam and adapted to discharge between saiddisks in front of their aXes.

5. In a planter, the combination with a frame and a beam attachedthereto and having a bifurcated rear end, of furrow Aopener disks,supporting means for said disks secured to the beam, a rearwardly anddownwardly projecting bracket having its forward portion secured inthebifurcated rear end of the beam, said arm having a journal at itsrear end, a sleeve mounted to rock on the journal of the bracket andprovided with a curved bearing, a pair of yconnected covering blades,and a curved block secured to the connecting Vportion of said blades andadj ustably secured on said'curved bearing.

6. In a planter, the combination with a frame and a beam attachedlthereto and having a bifurcated rear end, of furrow opener disks,mountings for said disks connected with said beam, a bracket secured inthe bifurcated rear endof the beam and projecting rearwardly therefrom,covering blades mounted on said bracket to rock, and means for adjustingsaid blades vertically on their connection with said bracket.

In testimonyfwhereof, l have signed this specilication in the presenceof two subscribing; witnesses. Y f
